Step-by-step explanation:
6 problems= 8 seconds
1 problem = 4/3 seconds
16minutes= 960 seconds
960seconds÷4/3 seconds
=720
I'm not sure but I tried lol
Answer:
Width = 52 yards
Length = 208 yards
Step-by-step explanation:
(2 * 4x) + 2x = 10x
10x = 520
x = 52
52 * 4 = 208
(208 * 2) + (52 * 2) = 416 + 104 = 520 yards

Answer:
3) ½ chance
4) 60 times
Step-by-step explanation:
<h3><u><em>
3) Theoretically, if the spinner is spun 150 times</em></u></h3><h3><u><em>
how many times would you expect to get an</em></u></h3><h3><u><em>
even number?</em></u></h3>
<u><em></em></u>
There are 12 equal sections, getting an even numbers is a ½ chance. ( same as odd numbers)
The probability is ⁶⁄₁₂ or ½.
In addition, this is theoretical probabilty, it doesn't require experiments.
<h3><u><em>
4) Based on the experiment, if the spinner is</em></u></h3><h3><u><em>
spun 150 times, how many times would you</em></u></h3><h3><u><em>
expect to get an even number?</em></u></h3>
Getting a 2: ⁴⁄₆₀ or ¹⁄₁₅
Getting a 4: ³⁄₆₀ or ¹⁄₂₀
Getting a 6: ⁷⁄₆₀
Getting a 8: ³⁄₆₀ or ¹⁄₂₀
Getting a 10: ⁵⁄₆₀ or ¹⁄₁₂
Getting a 12: ²⁄₆₀ or ¹⁄₃₀
Chance of picking a even number using 60 tries:
⁴⁄₆₀ + ³⁄₆₀ + ⁷⁄₆₀ + ³⁄₆₀ + ⁵⁄₆₀ + ²⁄₆₀ = ⁴ ⁺ ³ ⁺ ⁷ ⁺ ³ ⁺ ⁵ ⁺ ²⁄₆₀ = ²⁴⁄₆₀ or ⅖
Picking a even number using 150 tries:
⅖ · 150 = 60 times
Answer:
3_5/6 hours
Step-by-step explanation:
<u>2_ 1/3 = 2_ 4/12</u>
<u>1_3/4 = 1_6/12</u>
2_4/12 + 1_6/12 = 3_10/12
3_10/12 = 3_5/6
